Abstract: Several more or less severe infestations of Berberis thunbergii by Arge berberidis in a wide area around Arnhem, in the province of Gelderland, show that this sawfly species is no longer as rare as it was prior to 1990. A phenogram of the species is presented based on almost daily observations during late 1997, and 1998. Larvae from defoliated Berberis bushes were seen to migrate to and finish development on nearby Mahonia aquifolium. A single specimen of the eulophid Cirrospilus vittatus was reared from an egg batch collected in the field.
